At each of the four locations marked, indicate how a gene may be regulated by selecting from the choices given. Some answer choices may fit into more than one position; however, you should use each answer choice only once. Choices given: Alternative splicing within the gene sequence can lead to different forms of mRNA. A promoter region can be blocked by another protein. Histone deacetylation can prevent DNA from unwinding. A regulatory region can be bound and increase transcription rates.arrow_forward
